IMPROVEMENT IN MAIL-BAGS.

Specification forming part of Letters Patent No. 171,250, dated December21, 1875; application filed v November 17, 1875.

To all whom it may concern:

Be it known that 1,]?0LYDORE S. THOM- SON, of Jersey City, in the countyof Hudson and State of New Jersey, have invented a new and usefulImprovement in Mail-Bags; and I do hereby declare the following to be afull, clear, and exact description of the same, reference being had tothe accompanying drawings, forming part of this specification, in whichmy invention is represented by a perspective view, a portion of the wallof the bag having been broken away to reveal the interior construction.

The object of the invention is to improve the construction of leathermailbags, so as to cause them to retain their form more perfectly, andto prevent them from wearing away at the edge around the bottom, bybeing drawn along over the ground when filled. To this end the inventionconsists in a mail-bag having its bottom formed with a turned-up flangearound its edge, which flange fits into or around the lower edge of theSides of the bag,

and is secured thereto by two or more rows of headed rivets that protectthe outside of the bag from injury.

In the drawing, B is the bottom of the bag, made in substantiallycircular form, and provided .with a turned-up flange, 1), around itsedge, as shown, said flange being, preferably,

. from an inch and a half to two inches and a half in width. S is thebag, into or over the end of which the bottom B is closely fitted, andto which it is secured by means of two or more rows of metal rivets, a.a, headed on the outside, or on both sides.

The leather at the flange b is thus of double thickness, and the twothicknesses, secured together along theirupper edge and also along theirlower edge, form a stout, strong, but sufficiently flexible rim at thebottom of the bag, which keeps the bag in shape whet-her filled orempty; and the heads of the two rows of rivets effectually protect theoutside of said rim from injury when the bag is dragged along theground.

A narrow rim secured together by a single row of rivets will not answerthe purpose. as it will turn under and allow the bag to get out ofshape, and the unprotected leather to drag on the ground. I Three rowsof rivets will answer the purpose, but practically no better than tworows, although more expensive.

With two rows of such rivets as are ordinarily used in mail-bags, and aflange wide enough to give each row a good hold upon the leather withoutbeing too near the edges thereof, every essential condition isfulfilled.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

A mail-bag having a bottom with turned up circumferential flange, andhaving sides overlapping said fiange, and secured thereto by two or morerows of metal-headed rivets, substantially as described.
